Is it true that women only fart 25% as much as men?

Gas forms in your large intestine when bacteria ferment carbohydrates — fiber, some starches and some sugars — that aren't digested in your small intestine. Bacteria also consume some of that gas, but the remaining gas is released when you pass gas from your anus.
Depends on what you eat regarding who does more. Not gender related.

27%

I read somewhere that they fart more than men.

Pft.. them wilderbeasts fart like hippos

no. there is an average. some are less, and some are average, and some are above, regardless of gender.

I know where this is going..
next will have Greta and AOC saving the cows and culling men to save the ozone

How would one measure this statistic 🤔?

Not in my experiemce....my wife farts a lot more tam I do.

Nope..,

The average person farts 10 times a day

If a study has been done into that, I need no more evidence to know that some researchers need to lose their jobs.

Who tf studies that?
